TECHNICAL FIELD

The present disclosure relates generally to a system and method, more particularly, to a system and method for generating edible decorative items.

BACKGROUND

Some food products, such as cakes and cookies, are popular items for special events, including, for example, a birthday, a wedding ceremony, and an anniversary ceremony. People typically make the cakes at home, but more often, order the cakes from a bakery. To add more happiness to the special events, people sometimes wish to add decorative items, such as special words, symbols, images (e.g., pictures or photos), flowers, etc., on top of the cakes. These decorative items are typically produced on the cakes by manually applying a layer of color icing and/or frosting to the top surface of the cakes using an applicator, such as a nozzle. Manual decorating of the cakes, however, entails excellent skills, and is labor intensive.

Alternative systems have been developed to make cake decoration easier and more convenient. Some systems use a conventional printer or photocopier to form an image on an edible medium, such as an edible paper, and then place the edible medium, on which the image has been formed, on the cakes. This type of system enables a user to apply virtually anything that is desirable to the cakes.

These conventional printers and/or photocopiers are typically equipped with conventional ink cartridges that are originally designed only for normal document/photo printing/photocopying purposes, but are not designed for the food industry. In the current market, many ink cartridges for printing such decorative items in food industry either simply replicate the design of the conventional ink cartridges, or use recycled ink cartridges from the document/photo printing industry.

When used in the food industry, these conventional ink cartridges filled with edible inks pose a serious health concern. A conventional ink cartridge is typically provided with a sponge within an ink reservoir. The sponge provides several functionalities, among which is to keep a pressure balance and to absorb and hold the ink so that the ink does not leak from the reservoir or does not dry up quickly. However, the sponge provides a place for molds, yeasts, and/or bacteria to grow under room moisture and temperature. Although the molds, yeasts, and/or bacteria grown in the sponge may not be seen by naked eyes, they may contaminate the edible ink. Thus, when the edible ink is used in printing edible decorative items, which are subsequently consumed by a consumer, the consumer's health may be seriously threatened. In addition, when consumers learn of the possible existence of molds, yeasts, and/or bacteria in the ink that is used in forming the edible decorative items, they may no longer feel comfortable in purchasing food products with edible decorative items. This may damage the image of the store or bakery that sell the food products having the edible decorative items, which may result in a decline in the business of the store or bakery.

The present disclosure is directed toward improvements in the existing technology for generating edible decorative items in the food industry.

During printing, air may flow into ink cartridge 240 through air vent hole 300, air tube 270, and air control valve 330. During printing, air control valve 330 may open to allow air to flow into space 260 where ink is stored. When printing is not performed, air control valve 330 may maintain a closed state. Air may not be leaked into ink cartridge 240 when air control valve 330 is closed.

Ink cartridge 240 may include an ink exit port 340. Ink cartridge 240 may also include a plug 350. Plug 350 may be applied to ink exit port 340 to cover ink exit port 340. A user may push plug 350 into ink exit port 340. Plug 350 may occupy and cover the entire ink exit port 340. Although shown as separate elements, ink exit port 340 and plug 350 may be integrated as a single unit. Plug 350 may be made of a soft and/or elastic material, such as a silicon rubber. When ink exit port 340 and plug 350 are integrated as a single unit, the entire single unit including ink exit port 340 and plug 350 may be made of the soft and/or elastic material, such as the silicon rubber. Ink cartridge 240 may further include a cover 360. Cover 360 may be applied to cover the plug 350 and ink exit port 340, thereby further preventing ink leakage.

FIG. 4 is a schematic perspective view of ink cartridge 240 consistent with disclosed embodiments. As shown in FIG. 4, air tube 270 is provided within space 260 enclosed by housing 250. Air tube 270 is at least partially submerged in ink when space 260 is filled with ink. Ink cartridge 240 may include an ink filling hole 370, through which ink may be filled into ink cartridge 240. After ink is filled into ink cartridge 240, ink filling hole 370 may be sealed, for example, by covering ink filling hole 370 with a tape, to prevent ink leakage.

Housing 250 may be made of any suitable materials, including, for example, plastic, metal, or polymer. In one embodiment, housing 250 may be made of a transparent or translucent material so that the color ink stored within ink cartridge 240 may be partially seen from outside of ink cartridge 240. A user may easily inspect whether there is ink in ink cartridge 240, and how much ink remains in ink cartridge 240. In one embodiment, ink cartridge 240 may include volume marks 252 on the outside body of housing 250 to indicate the volume of ink. Ink exit port 340 may be made of the same material used for housing 250, or may be made of a different material than that of housing 250.

System 10 may display the edited image in a preview area for the user to preview the image (Step 1560). The user may decide whether the edited image has achieved the desired effects. System 10 may save and/or print the image based on the user's input received through user interface 40 (Step 1570). For example, the user may save the image using save button 815 from system menu 810, or print the image using print button 1420. An edible decorative item is generated when the image is printed on edible image formation medium 90 using printer 60 and spongeless ink cartridge 240 provided in printer 60. The edible decorative item may be placed on food product 100, such as a cake.

The disclosed system may be employed in any commercial store or bakery for generating edible decorative items for food products, such as cakes and cookies. The disclosed system may also be employed at home for personal use. The disclosed spongeless ink cartridge may be employed in any image forming apparatus, including, for example, inkjet printers, laserjet printers, and photocopiers. Compared to a conventional ink cartridge, the disclosed ink cartridge does not have a sponge to take up a substantial space in the ink cartridge. Therefore, more ink may be stored in the disclosed ink cartridge than the conventional ink cartridge. As a result, the disclosed ink cartridge may require less frequent refill of the ink or replacement under the same usage condition as compared to the conventional ink cartridge.

With the disclosed air tube having the air control valve, ink flow during printing may be effectively and accurately controlled. The employment of the disclosed air tube having the air control valve may also eliminate the use of a sponge, making the ink cartridge spongeless.

With no sponge disposed within the disclosed spongeless ink cartridge, the chance for mold, yeast, and bacteria to grow may be significantly reduced. Therefore, the hygienic condition of the edible decorative items printed using the disclosed spongeless ink cartridge may be significantly improved as compared to that of the edible decorative items printed using the conventional ink cartridge.

With the disclosed plug, the ink exit port may be sealed tightly when the disclosed spongeless ink cartridge is not used for printing, thereby preventing ink from being exposed to outside air and consequently reducing the speed of ink dry up. As a result, the life cycle of the disclosed spongeless ink cartridge may be significantly elongated as compared to the conventional ink cartridge.

It will be apparent to those skilled in the art that various modifications and variations can be made in the disclosed system. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed embodiments herein. It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims.
